To all whom it may concern:

Be it known that we, JOHN M. YOUNG and CLARENCE M. SYMoNns, citizens of. the

onal Cans, of which the folltjlwing is a specification.

Our invention relates to improvements in machines for soldering the heads upon square, rectangular or "polygonal cans by fusing solder previously appliedto the can bodies near the ends thereof.

The object of our invention is to provide a. square, rectangular or polygonal can fusing machine of a simple, eflieient and dare: blc'construction by means of which square rectangular or polygonal cans may be rapidly, cheaply and perfectlyv solder'edby fusing solder ribs or beads previouslyyapr. plied to the can bodies near the ends thereof.

Ourinvention consists in the novel construction of parts and devices, and in the novel combinations of arts and devices,

, herein shown and descri ed, by which this ob'ect or result is accomplished.

the accompanying drawing forming a part of this specification, Figure 1 is a p an view of a square, rectangularpr polygonal can fusing machine embodying our inven-,

tion. Fig. 2 is-a side elevation. Fig. 3 is an end view. 4 is a detail horizontal section on line 44 of=Fig. 2. Fig. ,-5 is a dctail vertical section on line'5,5 of -Fi 1. Fig. 6 is an enlarged detail plan view 0 the can turning mechanism and Fi 7 is an enlarged detail section on line 7 of Fig. 1.

In the drawing, A represents the frame of the machine. B is a can supporting track or plate along which the cans X are conveyed or moved in an upright position withthc head mto be soldered lowermost, and resting flat'against' the can track or plate B, the same being preferably of a loop form and having circular or curved end ortions B at eachend. I D is an endless exible can oonveyer or chain furnished with a series of can pusher arms (2 for pushing the cans along the track B, the same being operated by horizontal pulleys or sprocket wheels D D having Specificationof Letters Patent. Application'flled August 1, 1908.; Serial o. 328,752.

vertical shafts lD -D .jo'urnaled upon the frame of the machine.

C is a track for supporting the cancarrier I 1 or chain D, the same consisting preferably of an angle iron secured to the ame of the machine, and C is a track or guide for supporting the free ends of the canpusher arms I l F F are adjustable ,guides for the cans'between which the cans move as they are conveyed over the track orplate B by the can conveyer or chain D. These can guides F F are supported on brackets F attached to the frame of themachine and adjusted to and from each other, according to the size of the cans being 0 erated upon, bythe adjusting screws 7. "T e can pusher arms. d. are each furnished with an upright ar'm al to engage,

the can and prevent any ten'denc for it tel "tip as it is pushed-alon .the trac and thus insure the lower head 0- the can resting flat tangular cans like oyster cans, for example, which are of considerable height and narrow in thickness. The can guides F preferably have half round faces to engage the cans I At each side of the machine,"the can track; orplate B is provided with a circular recess to receive a rotating can turning plate G which operates in conjunction with the con 4 veyer D and its pusher arms (Z to give the cans aquarter turn after the two opposi e seams thereof have been fused so as to bring the remaining seams thereof 1n positlon for fusing These rotating can turning plates.

from theconveyer .D, and preferably have a higher surface speed than the conveyer, to facilitate the turning of the cans. At the point where the rotating can turning plates G are located,-the inner can guides F are provided with circularly curved portions F 'to cooperate, with the rotating can turning plates H H are heater pipes having jet orifices h for projecting flame against the solder rib .100

or bead m on the can body near the lower end thereof and against the scam to effect the fusing operation. These heater pipes are arranged parallel and adjacent to the ath of the cans as they are above and aral el to the can track B. The jetpri cos b preferably project downwardly or have a downward. incline sons to project the flame properly against the solder to be fused and the joint or seam to be soldered. The can track B is supported on adjusting screws Z2 so that it may be adjusted up and down as required. The heater pipes H are adjustably secured in position by means of clamps H and. clamp bolts H The ends or curved portions B of the can track B are provided with perforations b and below this curved portion is arranged an air reservoir B so'that cold air may be projected up against the cans after the fusmg operation to cool the seams while the can seams remain in a horizontal position. To facilitate the cooling operation, this curved portion B of the can track B is pro- 1 vided with ribs or rails to better admit the air blast against the heated and freshly soldered seam of the can.

The can conveyor or chain D is driventhe driving shaft is? to one of the rotary can turning disks or plates G through a gear 9 on the driving shaft K meshing with a gear 9 on the countershaft 9 having a sprocket wheel 9 and chain engaging a sprocket wheel on a horizontal shaft 9" which is furnished with a sliding or adj ustable friction roller 9" engaging a friction disk 9' on the upright shaft G of the rotary can turning disk or plate G. By adjusting the friction roller 9 in or out, the can turning disk or plate G can be given any required speed of rotation in respect to the speed of the can conveyor or chain D which may be necessary to properly give the cans a quarter turn after the two opposite seams thereof have been fused or soldered. and thus present the two remaining sides or seams thereof to the action of the fusing or heating pipes which are arranged parallel to and on each side of the path of the cans. The shaft 9 is journaled at-its inner end on a bearing 9 through which the upright shaft G extends. The friction roller 9" is adjusted radially in or out in respect to the friction disk (7 by means of an adjusting screw 9 having a hand wheel 9 and furnished with a nut or threaded sleeve g having an arm 9 engaging a curved collar or hub g on the friction roller 9 If the cans to be soldered are square or have all their four sides equal, all the can guides F are adjusted the same distance apart, but in soldering cans like oyster cans where two of the sides are much shorter than the other two, the can guides F for soldering each pair of sides of the can are preferably correspondingly adjusted, those on one side of the can turning disk or plate G being farther apart and those on the othersido closer together.

- M is a gas pipe for supplying fuel to the burner pipe H and N compressed air pipes for supplying compressed air to the burner pipe and to the cooler reservoirs B".

The shaft G oftho can turning disk G. which is geared to the driving shaft, is furnished with a ulley g, and through a belt or rope and pulley (7 communicates motion to the upright shaft G of the other can turning disk G on the opposite side of the machine.

In operation, the cans are placed on the can track or plate B at B in position to be engaged by the arms d of the can conveyor chain D and are moved slowly along between the hcater or flame projecting pipes H, thus fusing the solder a) on the can body X above the can head flange and causing the same to flow down into the scam and thus form a perfect solder joint. After two opposite sides of the rectangular can have thus been fused or soldered, the cans are moved. by the pusher arms (Z of the conveyor D onto the can turning disk G, and by its action, in cooperation with the conveyor 1) and pusher arm (Z, given a quarter turn, thus bringing the two remaining sides of the cans adjacent to the heating pipes H so that the two remaining seams are fused and soldered. The cans then pass. onto the curved portion B of the can track or plate B and the hot and freshly soldered end seam of the van is thus cooled and the solder set. The operator then turns the can end for end at B and the operation is repeated for the other end of the can by the remaining half of the machine, after which the cans are automatically discharged from the machine by the inclined can discharging arm P.
